BEIJING – To the chagrin of Shanghai city residents, there’s more “pork chop soup” on the menu for the foreseeable future.

More than a week since authorities in Shanghai started pulling thousands of dead pigs from one of the city’s major waterways, the Huangpu River, municipal authorities in that city of 23 million are continuing to pull hundreds of carcasses from its waterways each day, bringing the total since last week to over 13,000.

Workers on Sunday pulled nearly 500 pigs from the Huangpu, bringing the total found from that river alone to over 9,500. The Huangpu River supplies over a fifth of Shanghai’s drinking water.
